PURPOSE: The purpose of this study is to investigate fatigue and its related factors in cancer patients receiving radiotherapy. METHOD: The subjects of this study consisted of 98 patients receiving radiotherapy. Subjects were recruited from C University Hospital radiation oncology unit located in Gwangju from March to May, 2001. Questionnaire and medical records were used for data collection. The obtained data was analyzed using SAS program that included descriptive statistics, t-test, ANOVA, Post-hoc test(Fisher's LSD) and Pearson's correlation coefficients. RESULT: The fatigue perceived by the subjects was middle level (5.59 +/- 1.59) and 72.4% of them reported greater than 5 points. The subjects in no religion, low income, and spouse caregiver groups experienced the higher fatigue than another groups, respectively. The subjects in nasopharyngeal cancer, head & neck radiation site, and analgesics medication groups did, experience fatigue as well. The fatigue not only positively correlated with symptom distress, disruption of usual activity, sleep dissatisfaction, and mood state, but also negatively with less family support. CONCLUSION: Cancer patients receiving radiotherapy experience the middle level of fatigue and it correlates with the multi-dimensional factors. However, further research is needed to identify the changes in fatigue over the radiotherapy period through longitudinal design and to develop nursing intervention for fatigue decrease.

A histopathologic study including iramunohistochemical stains was made in 30 patients who were presented with gastrointestinal lymphoma. The occurrence was 13 in the stomach, 8 in the ileocecum, 7 in the small intestine and 2 in the colon. The disease more frequently affected males than females and the average ages were 53 years in the patients of gastric lymphoma and 44 years in the patients of intestinal lymphoma. Gastric lymphomas were usually presented with a single lesion, and the antrum and/or body were the most common sites. But intestinal lymphomas were presented with a single or multiple lesion, and the ileocecum was the most common site. The most common gross type of gastrointestinal lymphomas was the ulceroinfiltrating type and most are of the diffuse large noncleaved cell type of B-cell lymphoma, histologically. There were 2 cases of T-cell lymphoma presented in the intestine as the superficially ulcerative gross pattern and diffuse immunoblastic cell type. The distinct MALToma was seen in only one case of stomach but the feature was partially remained in each two cases of stomach and intestine. Their coexistent findings may suggest that diffuse large of immunoblastic component arises through blastic transformation of the low-grade M ALToma component.

PURPOSE: The purpose of this study was to assess the importance and contribution of 9 nursing outcomes and their indicators that could be applied to cerebrovascular patients. METHODS: Data were collected from 175 neurosurgical nurses working at two university affiliated hospitals and five secondary hospitals located in Gwang-ju. The Fehring method was used to estimate outcome content validity(OCV) and outcome sensitivity validity(OSV) of nursing outcomes and their indicators. Stepwise regression was used to evaluate relationship between outcome and its indicators. RESULTS: The core outcomes identified by the OCV were Tissue Perfusion: Cerebral, Nutritional Status, Neurological Status, and Wound Healing: Primary Intention, whereas highly supportive outcomes identified by the OSV were Oral Health, Self-Care: ADL, and Nutritional Status. All the critical indicators selected for Fehring method were not included in stepwise regression model. By stepwise regression analysis, the indicators explained outcomes from 19% to 52% in importance and from 21% to 45% in contribution. CONCLUSION: This study identified core and supportive outcomes and their indicators which could be useful to assess the physical status of cerebrovascular patients. Further research is needed for the revision and development of nursing outcomes and their indicators at neurological nursing area.

PURPOSE: The aim of this research was to identify the relationships between occupational stress, ethical dilemma, burnout and turnover intention and the factors influencing turnover intention in hospital nurses. METHODS: The participants, 215 nurses, were recruited from two university hospitals located in two provinces of Korea. Data were collected through self-report questionnaires. Collected data were analyzed using descriptive statistics, t-test, ANOVA, Pearson correlation coefficients, and multiple regression with SPSS/WIN 22.0. RESULTS: Participants' scores for occupational stress, ethical dilemma, burnout and turnover intention were 3.96±0.45, 2.60±0.39, 3.71±0.70, and 3.50±0.90 respectively. The results show that the higher the score for occupational stress, ethical dilemma, and burnout the higher the score for turnover intention. The most important factor influencing turnover intention was burnout (β=.42, p < .001), followed by position (β=.21, p=.001), educational level (β=.21, p=.007), ethical dilemma (β=.13, p=.020) in that order. These factors explained 43.5% of total variance in turnover intention (F=19.34, p < .001). CONCLUSION: Changes in hospital structural management systems and support strategies should be developed and operated, taking into account burnout, ethical dilemma, and personal characteristics of clinical nurses in order to reduce turnover.

PURPOSE: Primary pulmonary lymphoma(PPL) arising in the lung as the initial site is very rare. Authors experienced two cases of PPL and report the radiologic findings and clinical characteristics with a brief reviewof the literature. METHODS AND MATERIALS: Plain chest radiograph and enhanced axial CT scan of the chest were taken. We analyzed radiologic findings of the two cases and correlated with broncoscopic and pathologic findings. RESULTS: Plain chest radiograph showed a mass like consolidative lesion on RML without peripheral atelectasis. Chest CT scan revealed a mass like consolidation with airbronchogram and the absence of a hilar mass or thoracic adenopathy. Percutaneous needle aspiration and biopsy(PCNA and PCNB) of the RML mass confirmed B-cell lymphoma, in both cases. CONCLUSION: PPL must be included in the differential diagnosis of chronic alveolar consolidation such as bronchioloalveolar cell carcinoma.

OBJECTIVES: The aim of this study was to assess toxicities of cryoprotectants. METHODS: Toxicities of two cryoprotectants, dimethyl sulfoxide (DMSO) and 1,2-propanediol (PROH), were investigated using a murine embryo model. Female F-1 mice were stimulated with gonadotropin, induced ovulation with hCG and mated. Two cell embryos were collected and cultured after exposure to either DMSO or PROH. Embryo development was evaluated up to the blastocyst stage. Blastocysts were stained with bis-benzimide to evaluate the cell count and with terminal deoxynucleotidyl transferase mediated dUTP nick labeling (TUNEL) to assess apoptosis. RESULTS: The total cell count of blastocysts that were treated with DMSO at the 2-cell stage was significantly lower than that were treated with PROH (75.9+/-27.0) or the control (99.0+/-18.3) (p<0.001). On comparison of two cryoprotectant treated groups, the DMSO treated group showed a decreased cell count compared with the PROH treated group (p<0.05). Both DMSO (14.2+/-1.5) and PROH (11.2+/-1.4) treated groups showed higher apoptosis rates of cells in the blastocyst compared with the control (6.2+/-0.9, p<0.0001). In addition, the DMSO treated group showed more apoptotic cells than the PROH treated group (p<0.001). CONCLUSIONS: The potential toxicity of cryoprotectants was uncovered by prolonged exposure of murine embryos to either DMSO or PROH at room temperature. When comparing two cryoprotective agents, PROH appeared to be less toxic than DMSO at least in a murine embryo model.

Myxoid and round cell liposarcoma is a variant of liposarcoma characterized by a morphologic continuum in which tumor progression from low-grade myxoid to high-grade hypercellular or round cell areas may be observed. A 28-year old man presented with a painful skin colored subcutaneous mass on his left flank. The skin lesion was discovered about two months ago. Computed tomography revealed a well-defined tumor in the subcutaneous area without significant lymphadenopathy. A histopathologic study showed a nonencapsulated nodular growing tumor mass under the deep dermis composed of a mixture of atypical proliferating lipoblasts in a prominent myxoid stroma, occasional uniform round to oval shaped primitive nonlipogenic mesenchymal cells and plexiform, chicken wire shaped capillaries. Based on these findings, we diagnosed this case as myxoid and round cell liposarcoma. Because liposarcomas are large tumors of the deep subcutis or deeper soft tissue, they rarely come to the attention of the dermatologist. However, liposarcoma should be of concern, especially when rapid growing subcutaneous tumors are shown.

Peripheral primitive neuroectodermal tumor (pPNET), a rare, highly aggressive neoplasm of indetermined histogenesis, occurs typically in the soft tissues of the chest wall and the paraspinal region. Comprehensive diagnostic studies including histological, ultrastructural, immunohistochemical and molecular analyses have been stressed to diagnose this entity. We report a case of primary renal PNET which was incidentally found in a 59-year-old man who presented with generalized weakness for 4 months. He was diagnosed as a non-insulin dependent diabetes mellitus 15 years ago and has been made well by oral therapy. An ill-defined mass, measuring 3.5 3 cm, located in the left kidney and perirenal fat, was incidentally found by ultrasonogram during a renal diabetic examination. The mass was resected because of the unresponsiveness against one-year chemotherapy and radiation therapy. Grossly, a homogeneously solid, gray-white mass, measuring 2.8 1.8 cm, was noted in the mid portion of renal cortex. The mass showed severe adhesion to the perirenal fatty tissue. Microscopically, tumor cells were rather uniform, small round with scanty cytoplasm and often showed rosette formation. Ultrastructurally, they showed membrane-bound dense core granules, measuring 125~150 nm, intercellular junctions and microvillous cytoplasmic projections. The tumor cells were uniformly immunoreactive for neuron-specific enolase and were focally immunoreactive for CD99 (013), chromogranin, synaptophysin and cytokeratin. They were not reactive for S-100 protein, vimentin, Leu-7, leukocyte common antigen, desmin and smooth muscle actin. To our knowledge, this is the smallest renal PNET in literature.
